Dongguan Dechuang Chemical Co., Ltd. thermoplastic elastomer TPE, TPR polymer new material products are widely used in various toys, stationery, hardware products, casters, handles and other daily products, sealing strips, dust rings, wires and cables, auto parts, sports equipment and other fields. TPE rubber and plastic raw materials With regard to material hardness, TPR can provide materials with hardness ranging from 0 to 100 A for selection. At present, the processing of TPR is still mainly injection molding and extrusion, and the TPR materials can be blow molded TPE/TPR thermoplastic elastomer not only has the processing properties of thermoplastic, but also has the physical properties of vulcanized rubber, which can be described as an advantageous combination of the advantages of plastic and rubber. TPE/TPR is occupying the territory that originally belonged to vulcanized rubber. In recent ten years, TPE/TPR has been widely used in various fields: various doll toys, eraser dolls, bags and rubber, daily necessities, sealing strips and tension tubes, tension belts, wires, skin imitation products and other products. 1. environmental protection performance Although most TPR materials meet ROHS and EN71-3 testing standards, there are still differences in testing standards for toy products in different countries or regions. Some requirements do not contain PAHs polycyclic aromatic hydrocarbons and NP (nonyl), and some requirements do not contain substances of high concern to SVHC specified by REACH. And the environmental protection requirements above TPR can pass. 2. Excellent color matching and oil spray screen printing performance Most toy products are brightly colored, which requires high coloring of TPR grid materials. A good TPR has good toner dispersion and coloring performance (manufacturers should choose elastomer soft toner). Make the color realistic. In the process of spraying paint and screen printing, TPR also has excellent adhesion, so that the paint will not fall off when sprayed. Of course, the matching between TPR compound and ink and paint is very important, and the appropriate paint and ink should be selected according to the characteristics of TPR. 3. Excellent elastic performance and matters needing attention TPR material has good flexibility, high resilience, smooth and bright surface, and is not easy to crack. Specific product requirements can be reported to TPR material manufacturers, who can adjust the formula to achieve the desired results. TPR material is not recommended for products with hardness below 20A, and products with low hardness are easy to crack. TPE series products are recommended, and the hardness of TPE series can be below zero. Due to the demand of the market, the popular eraser doll can also use low-end TPR materials for injection molding. This kind of eraser doll should not choose TPR with high elasticity when selecting materials, because it should not only have the beauty of the doll, but also have the rubbing ability. Generally, this kind of material will try its best to keep its rubbing ability on the premise of ensuring the easy shape of the material. After several years' product improvement, Guofeng Plastic Industry has developed a series of eraser dolls, which is extremely cost-effective. 4. Good forming and processing performance TPR material has moderate fluidity, convenient molding and processing, and the injection temperature is 170~190℃, so it is not easy to have molding appearance problems such as shrinkage and burrs. TPR doll products with SBS as the main base material should strictly control the process, and it is better to mix materials without using high-speed mixing barrels and horizontal ones, and the time should not be too long. Generally speaking, the processing temperature should be controlled as low as possible. The shearing section is 180 degrees, and the latter sections are 160 degrees. When the temperature is over 200 degrees, SBS is easy to age, and the smell will increase a lot. The produced TPR granules should be cooled as soon as possible, and the smell should be volatilized, so as to ensure that there is not much heat when packing. In today's society, people pay close attention to everything about children, except food and clothing and toys. The TPR of toy wheel material produced by Dongguan Dechuang Chemical Co., Ltd. is wear-resistant, environmentally friendly and nontoxic. Rubber, which has excellent tensile and tear strength and excellent wear resistance, is the most common material for toy car tires. However, rubber needs to be vulcanized, the processing cycle is long, and waste materials are difficult to recycle again. In recent years, a kind of thermoplastic rubber (also called thermoplastic elastomer) TPR has gradually been widely used in various toy car tires because most toy car tires do not have too high requirements for load-bearing. TPE/TPR has excellent wear resistance, tensile strength, cushioning and shock absorption, and is thermoplastic, and can be directly injection molded without vulcanization, thus shortening the production cycle. Moreover, TPE and TPR are environment-friendly and nontoxic, and are more recognized by toy end consumers. Pet grooming comb is made of thermoplastic rubber TPE material. The handle material of this grooming comb is made of thermoplastic rubber TPE and PP, which has good grip, soft hand feeling, more labor-saving and comfortable use, environmental protection and no toxicity, and will not produce sex to skin. TPR material for extrusion vent dinosaur toys is modified by blending SBS as main substrate, processing oil and other additives. The modified material is characterized by moderate price, easy demoulding, high tensile strength and easy color matching. Most SBS dry adhesives have high viscosity and poor processability. By adding processing oil, the processability of the material was improved, and polymer resin (K resin, etc.) was added to enhance the strength of the material. Because SBS is the basic component of blending modification system, we used to call this kind of blending modification material TPR. Product features: high extensibility, high toughness, high elasticity, high transparency, bright surface, surface silk screen printing and oil spraying. Product use: Grape ball dinosaur pressure relief toys, high transparent toy dolls, suction cups, shoes, stationery, transparent rubber bands and so on. Dongguan Dechuang Chemical Co., Ltd. can directly test products for customers quickly and accurately, customize samples, and design new thermoplastic elastomer TPE/TPR polymer materials that meet customer product requirements.
